Water treatment resin generally refers to polymers with molecular formulas such as polyethylene, polystyrene, and polytetrafluoroethylene. Common ones on the market include American Rohm and Haas resin and British bleach resin. Wright resin, domestically produced Trier resin, has model numbers of 001*7 and 002*7.
Function: Displace calcium and magnesium ions from hard water to soften the water.
Principle: The principle of sodium ion exchange softening treatment is to pass the raw water through a sodium-type cation exchange resin to exchange the hardness components Ca2 and Mg2 in the water with the Na in the resin, thereby adsorbing the Ca2 and Mg2 in the water. Soften the water. For example, if RNa represents sodium resin, the exchange process is as follows:
2RNa
Ca2
=R2Ca
2Na
2RNa
Mg2
=R2Mg
2Na
That is, after the water passes through the sodium ion exchanger, Ca and Mg in the water are replaced by Na.
